29=item I don't like the new selection/popups/hotkeys/perl, how do I
30change/disable it?
31
32You can disable the perl extension completely by setting the
33B<perl-ext-common> resource to the empty string, which also keeps
34rxvt-unicode from initialising perl, saving memory.
35
36If you only want to disable specific features, you first have to
37identify which perl extension is responsible. For this, read the section
38B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
39example, to disable the B<selection-popup> and B<option-popup>, specify
40this B<perl-ext-common> resource:
41
42 URxvt.perl-ext-common: default,-selection-popup,-option-popup
43
44This will keep the default extensions, but disable the two popup
45extensions. Some extensions can also be configured, for example,
46scrollback search mode is triggered by B<M-s>. You can move it to any
47other combination either by setting the B<searchable-scrollback> resource:
48
49 URxvt.searchable-scrollback: CM-s
